The Lowdown
Alright, I’m gonna level with you. Honestly, the outlook for the next 16 days is pretty grim. There’s a long dry spell here, and I’m not seeing any real standouts worth paddling out for until maybe the very end of the run.
Right now, through this whole period, the wind is a persistent cross-shore mess, mostly from the ENE, and it’s blowing fresh at 15 to 22 mph most of the time. That’s kicking up a lumpy cross-chop that’s just making a mess of the waves. The swell is short-period, mostly around 6 to 8 seconds, and the combined energy is moderate, ranging from 123 to 788. The water temp is about average for the time of year, nothing unusual there.
The only break with any sort of recommendation is Kohala Lighthouse (Big Island), and it’s an advanced reef break that’s exposed to the north but the swell is coming from the ENE, so it’s not really in its pocket. It’s consistent, but the wind is never good – always cross or cross-on. The wave heights bounce around 4 ft to 8 ft, but with the short period and cross-chop, it’s just not shaping up. The biggest swell comes in around the 17th of August, with 8 ft faces and 8-second period, but still with that fresh cross-shore wind and poor conditions. It’s just not worth it.
Frankly, there’s a gap of no good surf from now all the way through the 16th of August. The only flicker of hope is a single record on the 4th of August afternoon that’s “marginal” – 5 ft swell from the ENE at 11 seconds, with a moderate cross-shore – but that’s a long wait for a maybe. That’s a groundswell, which is better for reefs like this, but the wind is still cross-shore.
Forget about paddle surfing. With this lumpy cross-shore wind and short-period swell, this setup is more interesting for kite surfing than anything else. Honestly, it’s a blank run. But hey, forecasts can change, and it’s not always this poor.

Information about the Kohala Lighthouse Surf forecast
The above surf forecast table for Kohala Lighthouse provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Kohala Lighthouse can be found by selecting the local surf guide option on the grey menu. Our Kohala Lighthouse surf forecast is unique since it includes wave energy (power) that defines the real feel of the surf rather than just the height or the period. If you surf the same spot (Kohala Lighthouse) regularly then make a mental note of the wave energy from the surf forecast table each time you go. Very soon you may start to choose your surf days based on the wave energy alone combined with our forecast of favourable offshore wind conditions. Our star ratings will help here and of course you will also find the usual wave height and period predictions on our surf forecasts as well as a full break down of the swell components under our advanced users option (to reveal that, click the little Einstein character under the tide times).
Further information to help with frequently asked questions about our surf forecast for Kohala Lighthouse may be found under the help tab on the top menu and also by moving your mouse over the question marks on the surf forecast table itself. Please always bear in mind that the forecast is for near-shore open water and local factors at each surf break influence the actual breaking wave height, such as the beach / reef profile, water depths offshore and shelter.
